STEM-WINDING WATCH.

SPIICIFICATION forming part of Reissued Letters Patent No. 10,531, datedAugust 4, 1885. Original No. 286.719, dated July 3, 1883. Applicationfor reissue filed March 14, 1885.

-To all whom it may concern.-

Be it known that I, DUANE H. Cannon,

of Waltham, in the county of Miiildlesex,v

State of Massachusetts, (formerly of Chicago, Cook county, Illinois,)did invent certain new and useful Improvements in Stem-Winding Watches,for which Letters Patent of the United States No. 280,719, were issuedupon the 3d day of July, 1883, which Letters Patent have been foundto beinoperative and invalid, and not to cover the invention set forth in-thespecification and shown in the drawings which were filed in the PatentOffice upon the 16th day of September, 1882,

1 preparatory to the obtaining of the said Letterslatent. Now,therefore,being desirous of reissuing the said Letters Patent, I have prepared,and do hereby declare the following'to be, a full, clear, and exactdescription of the said improvements, reference being had to theaccompanying drawings, in which- Figure 1 is a plan view of a watchcontaining my improvements, the dial being removed and the pendant and aportion of the center band beingin section; and. Fig. 2 is alike viewofthe same, showing the winding-and setting train in position for settingthe hands.

Letters of like name and kind refer to like parts in each of thefigures.

This invention relates to watches in which the winding and hands-setting train is operated entirely by means ofarotatable stem-arbor that isadapted to be moved longitudinally forthe purpose/of causing said trainto engage with the winding-wheel or dial-wheels. Heretofore in watchesof this class said winding and hands-setting train has-been normally inengagement with the winding-wheel and disconnected from the dial-wheels,so that an out- 0 ward movement of said stenrarbor has been necessary inorder to change the engagement of said train and adapt it for settingthe hands. Such construction. has required that there should be apositive connection between 5 the stem-arbor and the winding andhandssetting train to enable said arbor, when drawn outward, to efl'cctthe necessary change in the engagement of said train, which positiveconne'ct-ion has made saidstcni-arbor virtually a w watch movements andsists, principally,

part of the movementand' has prevented or rendered very difiicult andexpensive the changing of said movement from one case to another. i a

The object of my invention is to render cases readily interchangeable towhich end said invention conas an improvement -in stem winding andsetting watches, in a winding and hands-setting train which isadaptedlto be placed in engagement with the windingwheel or thedial-wheels by the longitudinal movement of a stem-arbor that has nopositive connection with said train, suhs tantially as and for thepurpose hereinafterspecitied.

It consists, stem winding and setting watches, in a'wind; ing andhands-setting train which is adapted to be placed in engagement with thewindingwheel or the dial-w heels,'and 'is normally' in engagement withsaid dial-wheels, substan o tially as and for the purpose hereinaftershown; It consists, further, as an improvement in stem winding andsetting watches, in awinding and hands-setting train which is adapted tobe placed in engagement with the winding- 5 wheel or the dial-wheels bythe longitudinal movement of a stem-arbor, and is normally in engagementwith said dial-wheels, substantially as and for the purpose set forth.

It consists, further, as an improvement in stem winding and settingwatches, in a windin g and hands-setting'train, which is normally inengagement with the dial wheels, in combination with a rotatablestem-arbor that has no positive connection with said train and isadapted to be moved longitudinally within the casestem to cause saidwinding and hands settingtrain to engage with the winding-wheel iandtobe simultaneouslydisengaged from said diai-wheels. substantially asand for the purpose hereinafter shown and described.

It consists, further, as an improvement in l stein'winding and settingwatches, in a winding and hands-setting train which is normally inengagement with the dial-wheels, in com-' bination with a rotatablelongitudinally-movable stem-arbor that has no positive connection iththe watch-movement, and when moved further, as. an improvement in. 6

' will cause disengaged from said dial-wheels and longitudinally togitu'dinally' to theout-erlimit ofits motionwill i permit saiditrain tobedisengaged from said winding-wheel and. engaged with said dialed toengage more grooves,

wheels, substantially as and for the purpose hereinafter specified.

Itconsists, further, as an, improvement in stem winding and settingwatches, in theoombinationiotf a -windin g and hands setting train whichis normally in dial-wheels, a stemarbor having no positive connectionwitlf said train, and an intermediate device which is adapted tocommunicate the longitudinal inward movement bfsa-id stem-arbor to saidwinding-train and cause the same to engage w'ithlthewinding-wheel, asand for the purposehereinaf-- substantially ter shown and described. p aIt consists, further, as. an improvement in stem winding and settingwatches, in a'watclr case provided with a longitudinally movablestem-arbor which is adapted. to engage with a suitably-constructed vhaving a positive connection therewith, and

a device for holding said stemarborin differ ent longitudinalpositions,.said device being independent of thewatch-movement andoutside 'of the movement-holding space in the case, substantially as andfor the purpose hereinafter specified.

It consists, finally, stem winding and setting watches, in a watch: caseprovided within its pendant with a longitudin all y-movable stem-arborwhich is adapt ed to engage with a suitably-constructed movement withouthaving positive connection therewith, and has within its periphery oneor or their equivalent, and a spring device secured within said-pendantand adaptwith the grooves of said stem arbor, substantially as and forthe purpose hereinafter shown.

In the annexed drawings, A represents the top plate of watch-movement,which plate is contained within the center band, B, of a watch-case thatis provided with the usual pendant b.

As this invention relates solely to the winding and hands-settingmechanisms, only the main winding-wheel O and one of the dialwheels, D,are shown of allof the timetrain;

Pivoted upon the plate A is a yoke, E, which at its pivotal centercarries a toothed wheel, F, and at each end has pivoted another wheel, Gor H, that is in engagement with and driven by said wheel F. theproportions of its wheels are such that by a slight oscillation of theformer upon its pivot the wheel G maybe caused to engage with thewinding-whee Q'whiie by a movement of said yoke-in an opposite directionsaid wheels Q and G will be disengaged and said wheel H will be causedto engage with the dial-wheel I). J ournaled within the plate A is anarbor, I,

When the stemarbor M is drawnoutward, so as to release the arm W, the spring K, being free to act,rcturnsthe shaft 1 to its former position, so as to relieve thewinding-wheel end of the yoke I E from the pressure of the spring arm iand i at the same time causes the dog t to bear upon the opposite end ofsaid yoke with ,sut ficient force to move said yoke to the oppositelimit of its motion 1 gage with the dial-wheels, the relative positionsof parts being then as-shown in Fig. 2.

and cause its train to en While the mechanism between the sternarbor andthe winding and dial wheels is prererably employed, my invention is notlimited to these particular devices, as any of the Wed hnownforms ofintermediate mechanism may be used; 7

In order that'the longitudinal movement of the stem-arbor M may beproperly limited and said arbor held with suflicient firmnessin eachposition without interference with its freedom of rotation,I employ aspring-retainer, O, which is preferably formed by partially splitting atube lengthwise and securing its whole endwithin the inner end of theaxial recess 1) of the pendant b and turning inward the ends of itssplit portion or forming at such point an internal bead. Said stem-arboris provided with two peripheral grooves, m and m, the first of which isengaged by the jaws 0 of said retainer when said arbor is at the innerlimit of its motion, while the second of said notches, m',is engaged bysaid jaws when said arbor is at the outer limit of its motion. Theinward spring of the jaws o is suflicient to cause them to hold thestem-arbor M in eitherof itsv longitudinal positions with the necessarydegree of firmnessto prevent accidental displacement, but does notprevent said arbor from being easily" moved from: one to the other ofsuch positions, when desired. When the stem-arbor is drawn to the outerlimit of its motion, its inner end proiects into the pinion L only sofar as to enable it to rotate said pinion for the purpose ot' settingthe hands, and in such position oflers no obstruction to the removalfrom or insertion of a movement within the case, and is ready for use.as soon as a movement is in place.

Heretot'orcin watches of this cl a'ssthe means for limiting thelongitudinal movement of the stem-arborhave been'plaeed in the movement.By this improvement the limiting devices are contained wholly in thecase instead of the movement, whereby the case is always ready for theinsertion of any movement designed for it, and such operation is aseasily efl'ected as in case of a key-winding watch.

In hunting-case watches, when a locking spring or catch is employed forfastening the front cover when closed, the groove m of the stem-arbor Mshould be wide enough to per- I mit said arbor to have sufiicientadditional inward motion to enable it to act as a pushpin in opening thecase.

Instead Lof the peripheral grooves in said stem-arbor, a singleperipheral ei'ilargement or elevation may be termed thereon, and theends of such enlargement form limiting-shoulsuch purpose a screw havingan eccentric or halt head may be arranged, so that when turned partiallyaround the largerport-ionof such screw-head will bear upon the armi andproduce the same effect as would the'lon'gi tmlrnally-inwar'd movementof the stem-arbor.

In describing the stem-arbor as having no positive connection with thewinding and hands-setting train, I wish to be understood as meaning suchconstruction as causes said arbor to be contained within the pendant cfa watch-case and to-form part of such case, in eontradistinction to anorganization in which the stem-arbor is journaled in the movement and isso connected therewith as to be removed from the case with saidmovement.

In my construction the winding-arborforms part of the case, while inother organizations it formsvpart of the movement.

Having thus described my invention, what I claim is 1. As an improvementin stem winding and setting watches, a winding and hands-setting trainwhich is adapted to be placed in engagement with the winding-wheel orthe dialwheels by the longitudinal movement of a stem-arbor that has nopositive connection with said train, substantially as and for'the'purpose specified.

2. As an improvementin stem winding and setting watches, a winding andhands-setting train which is adapted to be placed in em gagement withthe winding-wheel or the dialwheels, and is normally in engagement withsaid dial-wheels, substantially as and for the,

purpose shown.

3. As an improvement in stem winding and setting watches, a winding andhands-setting train which is adapted to be placed in engagementwith thewinding-wheel or the dialwhee'ls by the longitudinal movement of astem-a-rbor,'and is normally in engagement with said dial-wheels,substantially as and for the purpose set forth.

4. Asan improvement in stem winding and setting watches, a'winding andhands-setting train which is normally in engagement with thedial-wheels, in combination with a rotatable stem-arbor that has nopositive connection with said train, and is adapted to be movedlongitudinally within the case stem to cause said windingandhands-setting train 'to engage with the windingwheel and to besimultaneously disengaged from said dial-wheels, substantially as andfor the purpose shown and described.

5. As an improvement in stem winding and setting watches,a winding andhands-setting train which is normally in engagement-with thedial-wheels, in combination witharotatablelongitudinally-movablestem-arborthathas no positive connectionwith the watch-movement, and when moved longitudinally to the innerlimit of its motion will cause saidwinding andset-ting train to bedisengaged from said dial-wheels and engaged with the winding-wheel, andwhen moved longitudinally to the outer limit of its motion will permitsaid train to be disengaged from said winding wheel and engaged ,withsaid dialwheel s, substantially as and for the purpose specified. 6, Asan iinprovelno'n'lgjn stem winding and setting watches, the combinationof a wind- 5 i ng and hands-setting trninwhieh is normally inengagemenbwith the-diul-wheels,- a. stemarbor hax' 3 no positiveconnection with said train, and intermediate device which is adapted toeonnn'unieate the lOllgitudines-l inlqwa rd niovement-of saidsteni-mbonto said winding-train and cause the same to engage with thewindingwheel substantially as and for the purpose shown and described.

In testimony whereof I hereunto set my hand this -2lstdzty of February,1885.
